Over the last 15 years there has been a paradigm shift in North America from hydrocarbon production from conventional, permeable reservoirs to ultra-low permeability, unconventional reservoirs. The exploitation of unconventional resources is made possible by injection of large volumes (millions of litres) of fluid at high pressures to hydraulically create a permeable fracture network in the reservoir. The process of hydraulically fracturing in some areas result in anomalous induced seismicity (AIS), and the fluids used may damage the reservoir and are viewed by some as potential contaminants. The potential for AIS and real or perceived problems associated with the large volume of fluid utilised are the most important issues currently facing sustainable development of unconventional hydrocarbon resources. Our research will contribute to: 1) prevention and/or mitigation of AIS due to hydraulic fracturing; 2) understanding fluid rock interactions to minimize reservoir and fluid damage; and 3) better characterisation of reservoirs to optimise exploration and production.

在过去的15年里，北美的油气生产模式发生了转变，从常规的、可渗透的油藏转向超低渗透的非常规油藏。非常规资源的开发是通过在高压下注入大量（数百万升）流体，在储层中形成水力渗透性裂缝网络来实现的。某些地区的水力压裂过程会导致异常诱发地震活动（AIS），所使用的流体可能会破坏储层，并被一些人视为潜在的污染物。AIS的潜力以及与大量流体使用相关的实际或感知问题是目前非常规油气资源可持续开发面临的最重要问题。我们的研究将有助于：1)预防和/或减轻水力压裂引起的AIS；2)了解流体与岩石的相互作用，以尽量减少储层和流体的损害；3)更好地描述储层特征，以优化勘探和生产。
